Click on messaging icon from main menu.
Click send message.
Instead of clicking text message click on pic/video message.
then you have 4 options TO: CONTACTS , TO Mobile#, To Email, And finally To Recent lict. Click on recent list and checkmark all the numbers you want deleted then click options bottom right corner then click delete.....
All finished hope this helps.

SOURCE: LG env2 will not save text messages

This happened to me. My problem was that i had a memory card, and i accidently put the save options for my pictures to my phone memory instead of to card memory. So it messed up my phone.

If you touch the message/picture/video you want to forward or save and hold your finger there, the options will come up! :)
